When the Rhön was still pagan, the devil still felt like the master of the area. Then St. Kilian came into the country, preached Christianity, and many were baptized. The devil was terribly annoyed. When it was even started to build a church in the valley, the devil became so angry that he dragged all the stones that had been brought in to build the church onto the Gangolfsberg and put them together so tightly that no one was able to apart. When people noticed this, they drew a cross on each brick. Then the devil had to keep his hands off. But the stones that he had previously brought up formed the Devil's Church.
In this devil's church, which was actually just a dark cave, the devil lived hidden and continued to mischief on earth. Unsuspecting farmers, berry hunters or hard-working forest workers had to make his acquaintance. He offered the good people money to win them over to his machinations and to keep them from going in the right direction. One day, however, someone trusted a pastor because he had a guilty conscience. The same day, some brave men went out with the priest to drive the devil out of his hiding place with prayers and holy water. And so it happened. At the cave it smelled bestial of sulfur and when the priest sprayed the holy water, the devil cursed out of the cave and has not been seen since. That is why the place is still called Teufelskeller today and sometimes it still smells of sulfur here today.
